Customer Ratings & Reviews

These batteries have outperformed cheaper versions of their own brand and other brands. Would recommend splurging a little more for these.

These batteries work great. Use them for our mechanical window shades. Only the second time I have had to replace them in several years.

Use these in my Blink Cameras. They are long lasting and quality batteries.

I use these batteries for my Zoom h5N audio recorder when I'm shooting videos and need external audio. These can last forever even when I have 4 audio sources recording for hours on end! Love them.

These batteries are the Best Buy for all batteries on the market. They are supercharged with lithium, giving you many years of maximum service.

Love these batteries for my Blink Doorbell. They last longer over the regular batteries.

I have a baby swing that is on batteries and these are truly working. Tried many different ones and they were not as strong as these are.

I have a large Nikon SLR and regular batteries do not stand up to the workload I put them through. These do the job very well. I can usually get 900 pics out of each 4 pack depending on flash use and temperature.

I find these to be the best batteries for using my hunting camera in both frigid cold and warmer temps. They hold a charge for longer periods of time than the standard batteries

A very good battery for my outdoor Blink camera. Last a long time in various degrees of weather.

I use this batteries on my surveillance camera's, great product.

After very short battery life with alkaline batteries in my Canon PowerShot I switched to Energizer Advanced lithium with much better results even for the much higher cost. This is my first experience with Energizer Ultimate, I bought them because Best Buy was out of stock on the less expensive Advanced. I hope the additional cost will be rewarded with longer battery life but it will be hard to measure.

I use these in my wireless security cameras and they last for about a year. I use rechargeable batteries in almost everything but those don't work so well for the cameras but these are great.

Batteries are so good i can go almost a year before i have to replace!

These Energizer lithium batteries last a long, long time. Additionally, they are very good in cold environments where a lot of batteries will be weakened in output and longevity.

These are the best batteries to use for almost anything. I especially like them for daughters insulin pump. It last a long time.

This energizer battery is the greatest it has long lasting power of time and it’s great for using and your electronics at all so great for flashlights the best battery you can buy

Great customer service and even better batteries!!

I'm impressed how durable are the energizer lithium batteries since realized those batteries are long life I started trust them and I think those are the best batteries ever.

Best batteries ever. Super long life in my Temp Stick and Blink cameras
